INTRODUCTION
Dear Customer:
Congratulations and thank you for purchasing a Wine Guardian® Humidifier. We believe it to be
the best wine cellar humidifier on the market and hope that you will agree.
This guide is intended to help the installer and owner of the Wine Guardian Humidifier to
properly install and maintain the equipment. In order to ensure optimal performance, the
equipment should be installed properly and have proper care and maintenance. Please read this
guide carefully, especially the safety instructions, and keep it for future reference.
Receiving, Unpacking and Inspection
This Wine Guardian Humidifier is shipped in a cardboard box. Each humidifier and humidistat is
factory assembled and tested prior to shipment. There are two models of the Wine Guardian
humidifier. The stand-alone model (see Figure 4.0) is supplied with its own grille, wall bracket
and transformer and is intended to be mounted separately and independently of the cooling unit.
The basic or integrated humidifier is intended to be mounted on a Wine Guardian cooling unit
(see Figure 5.0) and is supplied with an adapter.
Upon receipt and before opening the container, inspect the packing crates or boxes for obvious
signs of damage or mishandling. Write any discrepancy or visual damage on the bill of lading
before signing.
Find the packing slip and check for completeness of contents. Make sure it is the correct model
you ordered, including factory options and accessories.
Your Wine Guardian Humidifier has a humidistat that gets wired to the terminal strip on the
Wine Guardian unit and a drain line that requires piping to an open floor drain or condensate
pump. Inspect all equipment for any sign of damage or loose parts caused during transit.
Immediately report all visual or concealed damage to the carrier and file a claim.
NOTE: If this procedure is not followed, the shipping company may reject the claim and
the consignee may suffer the loss. Do not return the shipment to the factory.

General Description
The Wine Guardian Humidifier is a self-contained unit designed specifically for wine cellars. It
has been designed for easy installation and operation, either as a freestanding unit or mounted on
a Wine Guardian cooling unit. Wine Guardian uses a humidistat to sense and control the amount
of moisture needed to be added to the cellar. Humidifiers are not intended to remove moisture,
only add moisture. All components are of a high quality, standard commercial grade. The
humidifier operates with 24-volt power only and therefore does not require UL or CSA approval.
All wiring complies with NEC. The freestanding humidifier also comes with a sealed, plug-in
transformer and lead cord to allow the unit to operate independently of a Wine Guardian cooling
unit.
Wine Guardian Humidifiers are the evaporative drip pad-type. Air from the cellar is drawn over
a distribution pad that is saturated with water from a distribution tray. As the air passes through
the pad, it absorbs moisture through evaporation of the water. This raises the humidity of the
leaving air that returns to the cellar. Hot water is recommended for use with the humidifier,
however the system will work using cold water. Hot water increases the capacity of the
humidifier to evaporate the water as it passes through the pad. The hot water also leaves fewer
solids on the surfaces of the pad and flushes contaminants out of the pad. Excess water is
collected in the bottom trough and exits through the drain.
To avoid build-up of mineral deposits on the pad and potentially causing blockage of the air
flow, it is recommended that hard water be treated (filtered and softened). Install a 5- or 10micron in-line water filter ahead of the humidifier to keep dirt from fouling the inlet screen and
the evaporation pad inside. If the water has a high mineral content, a softener may be needed to
prevent excessive scale from building up too rapidly on the pad.
Additionally, to insure adequate wetted surfaces and to help flush away excess minerals, the
water flow is set to always have a flow of water to the drain. When operating, the humidifier will
use approximately 1 to 2 gallons of water per hour depending on the water pressure in the
building. About 60% of that will pass through and go out the drain. There is a strainer and an
orifice in the line to restrict the flow of water but a throttling valve may be needed to keep too
much water from going to the pad. All that is needed is a steady dripping of water out of the
drain to ensure adequate wetting and flushing of the pad media. Excess water does not negatively
impact the humidifier’s operation but neither does it contribute to more humidification. The drain
volume is too much for just a bucket. A gravity drain line should be piped to an open floor or
sink drain, or a condensate pump may be used where a gravity drain is impractical. This excess
drain water can be discharged directly onto the ground. The discharge of the drain can be
combined into the condensate drain from the cooling unit.
The humidistat, located in the cellar, will automatically turn on the humidifier whenever the
cellar humidity is below the set point and turns it off when the cellar humidity reaches set point.
The recommended setpoint is 55% for wine cellars. This humidity level is high enough to
prevent corks from drying out and low enough to prevent mold from forming. When the unit
turns on, the water solenoid valve opens and the fan turns on. When mounted and connected to a
Wine Guardian cooling unit, the humidistat also controls the main fan to circulate air to and from
the cellar.

CAUTION
CAREFULLY FOLLOW THE INSTALLATION INSTRUCTIONS INCLUDED WITH THE HUMIDIFIER.
REFER TO THE MANUFACTURER’S INSTRUCTIONS CONTAINED IN THE BOX FOR THE
HUMIDISTAT. WE RECOMMEND YOU KEEP THESE INSTRUCTIONS IN A FOLDER ALONG WITH THIS
GUIDE FOR FUTURE REFERENCE.
Size and Capacity
The Wine Guardian Humidifier uses a 10” wide x 11” high x 2” thick expanded coated
aluminum pad. Its rated output capacity for wine cellars is 60°F and 50%RH is 1.6 gallons per
day (gpd) with 60°F water supply, 3.3 gpd with 90°F water, and 5.1 gpd with 120°F water. The
weight of an operating humidifier is approximately 10 lbs. See Figure 1.0 dimensions.
OVERVIEW – refer to call-outs on drawing. See Figure 2.0
Adapter plates – metal plates used to mount the humidifier to the different sizes of Wine
Guardian cooling units.
Cabinet – the cabinet and access doors are constructed of 0.063” gauge aluminum with a powder
coated finish. This affords corrosion protection and an attractive, maintenance-free appearance.
Areas in contact with cold temperatures are lined with a dense, closed-cell insulation to prevent
condensation.
Distribution tray – the plastic water trough into which the water drips and is distributed evenly
over the drip pad through several holes evenly spaced in the trough.
Drain – collects excess water at the bottom of the pad and is piped to an external drain.
Electrical controls – most of the electrical components and controls are located inside the
humidifier enclosure. All wiring is done in accordance with the National Electrical Code. Wires
are numbered and color coded to match the wiring diagrams.
Evaporative drip pad – the expanded metal pad through which the cellar air flows and the
water drips down the surfaces.
Factory tested – all Wine Guardian Humidifiers are run in the factory and tested for operational
performance prior to shipment.
Fan – turns “On” and “Off” on signal from the humidistat when humidity in the cellar is
required. The fan draws air across the evaporative drip pad to absorb moisture.
Grille – for freestanding applications only. Used to separate the inlet air from the discharge air.
Orifice – small fitting with a very small hole in the center to restrict the flow of water.
5
Strainer – conical shaped stainless steel screen in a plastic frame to capture any sediment in the
water and keep it from plugging the orifice.
Water solenoid valve – opens and closes to control the flow of water into the distribution trough
on signal from the humidistat.

Safety
The Wine Guardian Humidifier uses only 24-volt power. However, that power comes from a
transformer, which uses 120-volt power. Therefore, before servicing the humidifier, be sure to
disconnect the main power to the cooling unit or to the humidifier.
The water supply to the humidifier may be hot. Turn off the humidifier and allow the water to
cool before servicing the humidifier.
CAUTION
METAL EDGES CAN BE SHARP AND CAUSE INJURY IF NOT HANDLED PROPERLY.
FAN BLADES CAN ALSO BE SHARP. DO NOT PUT FINGERS OR OTHER OBJECTS
INTO A MOVING FAN.
Installation
CAUTION
HUMIDIFIER MAY NOT BE INSTALLED WHERE IT MIGHT BE EXPOSED TO FREEZING
TEMPERATURES. IF THE COOLING UNIT IS MOUNTED OUTSIDE, THE HUMIDIFIER WILL HAVE TO
BE MOUNTED IN THE SUPPLY DUCT TO THE CELLAR INSIDE THE BUILDING OR MOUNTED AS A
FREESTANDING UNIT INSIDE THE CELLAR.
Pre-Installation Check
To check for any possible non-visible shipping damage, you may wish to test the unit before
actually installing it. To do so, remove the unit from its packaging and set it on any sturdy level
surface. If a freestanding unit, plug in the unit. If the unit is to be mounted into a cooling unit,
you need to wire the humidifier to the cooling unit and the cooling unit must be turned on. Then
turn on the rocker switch on top of the humidifier. The switch light should come on. This
indicates the unit has power. Set the humidistat above the room humidity. The unit should now
come on. The water solenoid should open and the fan should come on. Listen for any unusual
noise or vibration. Turn the humidistat below the room condition and the unit should go off.

Free Standing Installation with Stand-Alone Model
Figure 4.0
Stand-Alone Installation
1) Mount the face grille onto the humidifier box so that the separation plate slides in on top of
the fan and between the insulation on the sides. The two metal tabs (top and bottom) should
slide in between the insulation and the metal wall. Install two screws (top and bottom) into
the metal tabs to secure the grille in place.
2) Determine where unit will be mounted.
a. If wall mounted, use metal bracket provided. Secure bracket to wall with small hole on
top, larger hole on the bottom. Install humidifier onto the bracket with drain tube on
bottom. Secure the bracket to the humidifier at the top using the screw provided.
b. If shelf mounted, drill a 1” diameter hole in the shelf and mount humidifier with the drain
on the bottom through the hole.
c. If through-the-wall mounted, frame opening to fit outside dimension of unit. Allow for
drain line, flanges and water line. Slide unit into opening and secure into place (flanges at
front can be used). Fill in any gaps between the humidifier and the wall framing with
insulation.
10
NOTE: In all mounting arrangements make sure the humidifier is level and plumb in all
directions.
3) Install a ¼”water line from the water supply into the opening on the top of the humidifier.
Use flexible tubing to allow the unit to be rotated. A shut-off valve (not provided) is
recommended to isolate the humidifier from the water system when needed.
4) Install a ½” flexible drain line from the bottom of the humidifier to an open drain or connect
into the drain line from the cooling unit.
5) Install the humidistat on the wall where it is open to the cellar and can be read easily,
approximately 60 inches above the floor.
6) Connect the wires from the humidifier to the terminals on the transformer. Plug the
transformer into a 120v standard outlet.

Wine Guardian-Mounted (Integrated Installation)
NOTE: Integrated humidifiers can be mounted in either of the two side openings of the
cooling unit on the cooling or evaporator end only. Do not mount the humidifier on the
condenser end of the unit. If a duct connection is in that position, move the duct
connection to the top or other side.
1) Remove side access panel on the side of the cooling unit where you wish to mount the
humidifier.
2) Select the proper adapter plate for the cooling unit, (¼-, ½-, and 1-ton units use the same
adapter plate; 2-ton units require a larger adapter plate that must be ordered separately) and
install in the side opening using the screws from the panel removed above. The adapter plate
allows the humidifier to be mounted in either a forward position or back toward the center by
simply rotating the adapter plate 180 degrees.
3) Install a ½” flexible drain line from the bottom of the humidifier to an open drain or connect
into the drain line from the cooling unit.
4) Install a ¼” hot water line from the water supply into the opening on the top of the
humidifier. A shut off valve (not provided) is recommended to isolate the humidifier from
the water system when needed.

Mounting the Humidistat
Each Wine Guardian Humidifier comes with a humidistat and 25 feet of humidistat cable prewired to unit. The unit also comes with 5 feet of 3-wire, 24-volt power cable that connects to the
terminal on the side strip of the Wine Guardian Unit. (See Step 3 next page.) If you need to
remove the wires, please note the color-coding and replace the wires in the correct location.
After the wires are re-installed, test with a slight pulling motion back on the wire. If additional
wiring is needed, it can be spliced onto the factory-furnished wire. Be sure to match colors for
continuity and to insulate each wire separately with electrical tape.
12
CAUTION
BE SURE THAT EACH COLORED WIRE IS IN ITS PROPER COLOR-CODED SLOT ON THE TERMINAL
STRIP AND THAT THEY ARE TIGHT. MIS-CONNECTED HUMIDISTAT WIRING MAY RESULT IN
IMPROPER OPERATION AND/OR CAUSE DAMAGE TO THE UNIT AND HUMIDISTAT.
1) Mount the humidistat on a solid surface away from doors, corners, air outlets or other drafty
or heat generating equipment. Do not mount directly on an outside wall or wall adjacent to a
boiler room.
2) Use a piece of foam insulation behind the humidistat to insulate it from the hot or cold
surface. The recommended height is 4 feet to 5 feet above the floor. The humidistat is often
located next to the thermostat.
3) For the unit-mounted humidifier, wire the humidifier to the terminal strip on the Wine
Guardian cooling unit using the wire provided. Be sure to match the wire color with the color
code on the terminal strip.
Start-Up and Operation
Now that the installation is complete, it’s time to start the unit.
1) Check to make sure all connections are secure.
2) Turn on the cooling unit if so mounted.
3) Turn on the rocker switch on the top of the humidifier.
4) Test the operations by setting the humidistat above the room condition. The humidifier
should come on, the water solenoid should open, and water should flow. It may take a few
minutes for water to appear in the drain line.
5) Set the humidistat below the room condition and the humidifier should shut off.
6) Follow the manufacturer’s directions with the humidistat for troubleshooting.
Humidistat
CAUTION
THE HUMIDISTAT IS USED IN A BROAD RANGE OF APPLICATIONS AND THE MANUFACTURER’S
LITERATURE CONTAINS INFORMATION THAT MAY NOT BE SPECIFIC TO YOUR WINE CELLAR
APPLICATION. REFER TO THE MANUFACTURER’S INSTRUCTIONS CONTAINED IN THE BOX WITH
THE HUMIDISTAT. WE RECOMMEND YOU FOLLOW WINE GUARDIAN’S HUMIDISTAT
INSTRUCTIONS AND SIMPLY RETAIN THE HUMIDIFSTAT MANUFACTURER’S INSTRUCTIONS IN A
FOLDER ALONG WITH THE WINE GUARDIAN OPERATION AND MAINTENANCE MANUAL FOR
FUTURE REFERENCE.
1) Disregard the wiring diagrams shown within the manufacturer’s instructions. Refer to the
wiring diagram shown in this guide on page 8. The remote outdoor sensor is not required for
wine cellar applications and should not be programmed for use.
2) Set the humidistat at the desired humidity, recommended between 55% and 60%, which is
adequate to prevent drying out of corks and not so high as to risk mold growth. Overhumidifying can cause mold growth and sweating on surfaces and loosening of labels on
bottles.
13
NOTE: The humidifier can only add moisture, not remove it. Removal, or
dehumidification, is a function of the cooling system as it lowers the temperature of the
air below its dew point at which moisture condenses out onto the cooling coil and into
the condensate drain. Therefore, the humidistat will only control the addition of moisture.
The amount of humidification and dehumidification is mostly dependent on the relative humidity
of the ambient air and on the quality of the insulation and vapor barrier in the cellar. In southern
climates, humidification is not normally the dominant need, just cooling and dehumidification. In
northern, colder climates, winter weather will result in low humidity levels indoors. This requires
more need for humidification to keep the moisture level in the cellar up above 40%, especially in
higher elevations where the air is drier.

Maintenance
CAUTION
BEFORE PERFORMING MAINTENANCE ON THE UNIT, READ AND UNDERSTAND THE SAFETY
INFORMATION CONTAINED IN THIS GUIDE.
The Wine Guardian Humidifier is designed for minimal maintenance. Never oil any part of the
humidifier. Always disconnect the electrical power to the humidifier and the cooling unit if used.
A regular maintenance program prolongs the life of the humidifier and maintains the humidity in
the cellar. Frequency of cleaning and replacement of the drip pad depends on the inlet water
conditions and the cleanliness of the cellar air. The drain system may also trap dust and dirt.
When water no longer stays on the pad or mineral build-up has started to reduce airflow, the pad
needs to be replaced.
Suggested maintenance schedule:
Monthly – may change to quarterly depending on experience with individual cellar:
√ Check drain – clean is needed – confirm steady flow of water while in operation
√ Check for noise or vibration
Yearly – in addition to above:

Figure 7.0
15
CAUTION
BEFORE STARTING WORK, BE SURE THE POWER TO THE WINE GUARDIAN COOLING UNIT AND
HUMIDIFIER ARE TURNED OFF.
MAKE SURE THE POWER CORD IS DISCONNECTED FROM THE POWER SOURCE.
1) Start by disconnecting the electrical power and shutting off the water supply.
2) Remove the access panel at the back of the humidifier.
3) Remove the drip pad and its plastic holder from the unit as an assembly by grasping the top
of the holder and pulling toward you, top first. Be sure the water feed tube is clear of the top
distribution tray.
4) Pull one side of the humidifier pad assembly frame toward you and remove the distribution
tray from the frame.
5) Slide the humidifier evaporator pad out of its frame. Clean the frame by twisting and flexing
it to loosen any calcium deposits, or use a putty knife.
6) Carefully scrape any mineral deposits from the tray and frame. Be sure the frame drain hole
has nothing blocking it. Remove any calcium deposits from the “V” notches in the
distribution tray but do not scrape off the granular coating from the bottom. This textured
surface helps ensure even water flow for maximum performance.
7) To clean the drain, pour some hot water mixed with a cleaning solution into the pan to flush
the dirt down the drain tube.
8) Check the humidifier pad. If dirty or excessive mineral deposits are present, install a new
evaporative pad. Replace the pad by sliding the pad back into the frame. Note: the pad must
be installed in the correct position. There is a colored spot painted on one end of the pad.
This is the top of the pad and must be installed with the colored spot UP, next to the
distribution trough. There is no inlet or outlet side for the airflow, only the requirement that
the colored spot be on the top.
9) Reattach the distribution tray to the frame by snapping it into place.
10) Reinstall the entire pad, frame and tray assembly, making sure the drain fits into the drain
fitting at the bottom and that the entire unit snaps into place and is held securely.
11) Be sure the water feed tube is aimed into the center of the tray.
12) Turn on the water and power.
13) Check for operation. See instructions under Start-Up. Be sure water is flowing into the
distribution tray and flows freely out the holes and over the pad. If water flow is not a steady
flow, the strainer and/or orifice may need service. See below.
14) Replace the humidifier access cover.
Humidifier Water Line Maintenance (See Figure 8.0)
1) Repeat steps 1 and 2 above.
2) Disconnect the water line at the inlet to the solenoid valve.
3) Remove the in-line strainer from inside the inlet fitting by using a small flat-bladed
screwdriver. Do not insert anything into the strainer that a sharp end on it as it might
penetrate the strainer and render it useless.
4) Clean the strainer by flushing under hot water or immersing in a demineralizing solution to
break down the mineral deposits. Inspect and replace the strainer if it cannot be cleaned or if
the screen is damaged.
16
5) Reinstall the strainer in the valve inlet and replace the tubing and tighten the compression
nut. Double wrench to prevent damage and leaks.
6) Disconnect the water line on the outlet of the solenoid valve.
7) Remove the orifice from the copper tube and make sure this small opening is unplugged.
8) Replace the orifice and reconnect the outlet water line. Double wrench to prevent leaking.
9) Reinstall the in-line strainer and reconnect the inlet water line. Double wrench to prevent
leaking.
10) Turn on water supply and reconnect electrical power to the humidifier.
11) Check to be sure the water supply tube is aimed at the center of the distribution tray between
the two center holes. This will ensure even distribution off water across the entire tray and
equally into each of the six holes, thereby evenly wetting the entire surface of the drip pad.

Directory of Terms
Ambient – the area outside the cellar. Could be another room, a basement, garage or outside.
BTU/H – British Thermal Unit per Hour is a unit of heat measurement. For example, one ton of
cooling equals 12,000 BTU/H.
Cellar – cubic feet per minute. Unit of measurement for the amount of air being handled by fan.
Condensate/Condensation – the water formed out of the air when it is cooled below a certain
temperature (called dew point). Often referred to as “sweating” on pipes and cold surfaces. This
water is collected at the bottom of the evaporator or cooling coil and drains out of the unit
through the drain line.
CSA – Canadian Standards Association
Evaporative pad – the wire mesh pad inside the humidifier that becomes coated with water as
the water drips down by gravity. Air being drawn over the pad by a fan causes the water to
evaporate into the air, increasing its moisture content.

Humidistat – an electrical instrument that measures the relative humidity of air and
reads in percent (%).
Humidity – relative humidity is the percentage of moisture in the air relative to the maximum
amount of moisture the air could hold at any particular condition. Relative humidity is what is
most widely used and is what a humidistat measured. For example, 100% relative humidity
means the air has as much moisture as it can possibly hold at that temperature. Absolute or
specific humidity is the specific amount of moisture (usually measured in grains of moisture per
point of air) in the air at a given air condition.
Heat Gain/Loss – the amount of cooling or heating expressed in BTU/H that is gained or lost
into or out of the wine cellar to the ambient space. It is this load that the Wine Guardian must be
